Add-DnsServerRecursionScope

Brian Lich|Last Updated: 3/28/2017

SYNOPSIS

Adds a recursion scope on a DNS server.

SYNTAX

Add-DnsServerRecursionScope [-Name] <String> [[-Forwarder] <IPAddress[]>] [[-EnableRecursion] <Boolean>]
 [-PassThru] [-ComputerName <String>] [-CimSession <CimSession[]>] [-ThrottleLimit <Int32>] [-AsJob] [-WhatIf]
 [-Confirm] [<CommonParameters>]

DESCRIPTION

The Add-DnsServerRecursionScope cmdlet adds a recursion scope on a Domain Name System (DNS) server. Recursion scopes are unique instances of a group of settings that control recursion on a DNS server. A recursion scope contains a list of forwarders and specifies whether recursion is enabled. A DNS server can have many recursion scopes.

DNS server recursion policies allow you to choose a recursion scope for a set of queries. If the DNS server is not authoritative for certain queries, DNS server recursion policies allow you to control how to resolve those queries. You can specify which forwarders to use and whether to use recursion.

The legacy recursion setting and list of forwarders are now referred as the default recursion scope. You cannot add or remove the default recursion scope, identified by name as dot (.).

EXAMPLES

Example 1: Add a recursion scope

PS C:\> Add-DnsServerRecursionScope -Name "ScopeInternal" -Forwarder 10.0.0.1,172.22.0.1 -EnableRecursion $True -PassThru
Name                                             Forwarder                                        EnableRecursion
----                                             ---------                                        ---------------
ScopeInternal                                    {10.0.0.1, 172.22.0.1}                             True

This command adds a recursion scope to the DNS server. This scope enables recursion and specifies two forwarders.

PARAMETERS

-AsJob

Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.

The cmdlet immediately returns an object that represents the job and then displays the command prompt. You can continue to work in the session while the job completes. To manage the job, use the *-Job cmdlets. To get the job results, use the Receive-Job cmdlet.

For more information about Windows PowerShell background jobs, see about_Jobs.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-CimSession

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

Type: CimSession[]
Parameter Sets: (All)
Aliases: Session

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ComputerName

Specifies a remote DNS server. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

Type: String
Parameter Sets: (All)
Aliases: Cn

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-Confirm

Prompts you for confirmation before running the cmdlet.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: cf

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

-EnableRecursion

Indicates whether to enable recursion.

Type: Boolean
Parameter Sets: (All)
Aliases: 

Required: False
Position: 3
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Forwarder

Specifies an array IP addresses of forwarders for this recursion scope.

Type: IPAddress[]
Parameter Sets: (All)
Aliases: 

Required: False
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-Name

Specifies a name for the recursion scope.

Type: String
Parameter Sets: (All)
Aliases: 

Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-ThrottleLimit

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

Type: Int32
Parameter Sets: (All)
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type: SwitchParameter
Parameter Sets: (All)
Aliases: wi

Required: False
Position: Named
Default value: False
Accept pipeline input: False
Accept wildcard characters: False

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters.
